摘要:

研究了裸散射矩阵奇异性和缀饰散射矩阵奇异性的物理意义。特别注意已被归因于众所周知的散射矩阵的有效拉格朗日量的场变换的不变性的作用。给出了各种模型中裸量和修整量的计算实例。

英文摘要:

The physical meaning of bare and dressed scattering matrix singularities has been investigated. Special attention has been attributed to the role of well known invariance of scattering matrix with respect to the field transformation of the effective Lagrangian. Examples of evaluating bare and dressed quantities in various models are given.
